IMPROVEMENT IN BOOT AND SHOE SOLE BUFFERS.

Specification forming part of Letters Patent No. [90,174, dated May 1,1877; application filed March 21, 1877.

To all whom it may concern Be it known that 1, FREEMAN WINSLOW, ofSalem, of the county of Essex and State of Massachusetts, have inventeda new and useful or Improved Shoe-Sole Buffer; and do hereby declare thesame to be described in the following specification, and represented inthe accompanying drawings, of which- Figure 1 is a side View, Fig. 2 alongitudinal section, and Fig. 3 an end view, of it.

The finishing of a shoe-sole at or near the vertex of the angle of theshank and heel as hereto practiced requires to be done with great care,especially in order not to injure or deface the front-edge 0f the heel.

The object of my invention is to enable such to be readily andthoroughly and more expeditiously effected.

My improved buffer consists of a disk or conic frustum, A, of wood, athick disk or conic frustum or cushion, B, of felt, not only glued,cemented, or fastened to one side of the part A, but covered on itsouter side with sand-paper a, or other suitable buffin g or abrasivematerial, the periphery of the felt being entirely without any suchcovering. The buffer so made is usually secured or screwed to a metallicshank, G, for fixing it to a rotary shaft or a bar, "1

junction with the front edge of the heel.

elastic property of the felt will allow of the Inusing the bulfer whileit may be in rapid revolution its abrasive surface is to be brought andborne in contact with the shoe-sole shank, and to-be moved across itnear and up to its The abrasive covering being carried in close, contactwith the surface to be finished, and up to the heel without danger ofinjury to or defacement of it.

It also causes the abrasive surface to readily adapt itself to thevarying curved surface to FREEMAN WINSLOW.
